Do you supply an evaluation certificate?

Yes. Every piece of jewelry is supplied with a valuation for insurance purposes.

We recommend that you contact an independent insurer. Report purchased items of value to your homeowners' or renters' insurance carrier.

Cape Diamond Exchange gives you the Evaluation certificate needed for insurance purposes.
Helpful hint: Compare rates and coverage before choosing a provider. In order to compare apples to apples ask each company the same questions. Ask them about all possible scenarios. Like: "What happens if all my valuable jewelry gets lost or stolen?" or "What happens if my wedding ring or diamond goes missing?").

Knowing your valuable and treasured jewelry is safely insured will give you peace of mind – and satisfaction in knowing you're protected.

Do you offer a warranty on the jewelry I purchase?

Yes. In staying true to our high standards of customer satisfaction, we offer a Lifetime Warranty to protect against manufacturer defects in craftsmanship. The warranty does not include normal wear and tear, or damages incurred due to trauma, negligence, lack of regular maintenance, loss, or theft. Please check the claws and prongs periodically to ensure the security of the diamond in the setting – as these can become loose.

How do I best care and maintain my new jewelry purchase?

We recommend that you have your ring cleaned, polished, and have the prongs inspected once a year. These services are complimentary.

Invoice, proof of purchase or your evaluation certificate must accompany the request each time.

We only ask that you cover the shipping and insurance to safely transport the ring to our facility and Cape Diamond Exchange will cover the shipment back to your safety.

Unfortunately we cannot offer this service to our international customers due to import taxes that are being charged when items are coming into South Africa.

Can I return an item if I don’t like it?

Yes, Only items that have been purchased online. Items that have been purchased online from our online store can be returned.

Items that were purchased in our store cannot be returned. The difference is of course due to fact that the item was viewed physically and were fitted on and when buying online one can always assume that it was not as envisioned.

Please note that returned items must be in their original, unworn condition, carrying our tag and accompanied by all original documentation or certificates. Due to their personalized nature, the following orders are nonreturnable: items that have been modified, engraved, or resized; items that have previously been exchanged; and custom designed jewelry.

We also limit some of our diamond rings, due to the risk of possibly compromising the diamond.
